wrapIter()

template<class IT >

_IterT< IT >::Iter wrapIter ( IT &&  source )

protected

wraps a given Lumiera Forward Iterator, exposing just a IterSource based frontend.

singleVal()

template<typename VAL >

auto singleVal ( VAL &&  something )

protected

an IterSource frontend to return just a single value once.

Warning

behind the scenes, a heap allocation is managed by shared_ptr, to maintain a copy of the wrapped element. When passing a reference, only a reference will be wrapped, but a heap allocation happens nonetheless

transform()

template<class IT , class FUN >

_TransformIterT< IT, FUN >::Iter transform ( IT &&  source, FUN  processingFunc  )

protected

pipes a given Lumiera Forward Iterator through a transformation function and wraps the resulting transforming Iterator, exposing just an IterSource.

This convenience shortcut can be used to build a processing chain; the resulting IterSource will hide any detail types involved.

Note

as with any IterSource, there is one virtual function call for every fetched element.

Note

obviously in case of a Map we'll get at most one result.
